Political science professor Su Yan accidentally traveled through the Tang Dynasty and was able to live broadcast the history of game theory to Li Shimin using a "celestial mirror" projection! When the "Prisoner's Dilemma" cuts through the blood of Xuanwu Gate, and the Three Provinces and Six Ministries become a "sand table of checks and balances of power," Su Yan uses mathematical logic to reshape the emperor's mentality. He argued with Fang Xuanling, deduced with Du Ruhui, and used behavioral economics to deconstruct the dilemma of the court. Let's see how Su Yan used modern knowledge as the fire and the official system of the Tang Dynasty as the furnace to compete in the whirlpool of power, ignite the spark of institutional change, and write a new chapter of a prosperous age where rationality and power are intertwined.
